hi, Jerry,
What is the problem with a sealer where intake vacuum is applied? I used permatex #2 on my Holley 1904 on my GMC 270 and have been having problems- likely vacuum leaks.

PS I found the answer from some other posts of Jerry's- the intake vacuum can draw the sealer into the engine, not a good thing.
